PlCKER-STAFF ROCKER AND CHECK.

SPECIFICATION forming part of Letters Patent No. 678,567, dated July 16, 1901.

I Application filed January 24, 1901. $erial No. 44,582. (No model.)

To ctZZ whom it may concern:

Be it known that I, ADOLOR HOGUE, a oitizen of the United States, residing at VVoonsocket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Picker-Staff Rockers and Checks, of which the following is a specification.

My invention relates toimprovements in looms; and it consists in a peculiar pickerstaff rocker and check, the novelty, utility, and advantages of which will be fully understood from the following description and claims when taken in conjunction with the accompanying drawings, in which- Figure 1 is a side elevation of my improved rocker and check. Fig. 2 is a View illustrating the rocker and check in plan and the picker-staff in section. Fig. 3 is a transverse section taken on the broken line 3 3 of Fig. 1.

Fig. 4 is an elevation illustrating the side of the rocker and check opposite to that shown in Fig. 1. Fig. 5 is a section taken in the plane indicated by the broken line 5 5 of Fig. 2 looking in the direction indicated by arrows. Fig. 6 is a section taken in the plane indicated by the broken line 6 6 of Fig. 2 lookingin the direction indicated by arrows. Fig. 7 is a diametrical section taken in the plane of the broken line 7 7 of Fig. at. Fig. 8 is a detail section taken in the plane of the broken line 8 8 of Fig. 3. Fig. 9 is a perspective view illustrat-ing the fulcrum-bolt, together with the bushing and the washer or wear-plate thereon.

In the said drawings similar letters of reference designate corresponding parts in all of the several views, referring to which A is the ordinary rocker-shaft of a loom.

B is a picker-staff.

G is the ordinary lug-strap for drawing the picker-stafi forwardly.

D is a rocker-arm which is fixed on the shaft A through the medium of a set-screw a, or other suitable means and is provided with a longitudinal transversely-disposed slot b, and E F are the members of my improved picker-staff rocker. These members E F are preferably of circular form, and the former is provided on its outer side with a lateral pin 0 and on its periphery with a thumb-piece (1, while on its inner side or face it has a plurality of serrations e, for a purpose presently described.

pioker-staff and on its inner side has serrations g, designed to engage those of the member E. The said members E F are connected by transverse bolts 72, which take through apertures i in the former and curvilinear slots j in the latter and are equipped with nuts 7;, as shown. By virtue of this construction it will be seen that when the nuts k are loosened the member F may be adjusted with respect to the member E to properly position the pickerstaff in the lay (not shown) of the loom and also that when the nuts are tightened and the serrations of the members pressed into engagement with each other thereis no liability of the section F moving with respect to the section E or the picker-staff casually working loose.

The picker-staff B is preferably connected to the rocker member F through the medium of a channel-iron Z, which straddles the staff, and a bolt m, which rests in the center of the said member and extends therethrough and also through the picker-staff and channel-iron Z and is provided at its inner end with a countersunk head '11 and at its outer end with a nut 19, as best shown in Fig. 7 of the drawings.

At a point off its center the member E of the rocker is provided with a transverse circular aperture q, in which is arranged a metallic bushing G. This bushing is provided, as best shown in Figs. 8 and 9, with an angular reduced portion 9", which rests in the slot b of the rocker-arm D, whereby it will be seen that the said bushing is held to the arm and against turning. The bushing forms an eccentric fulcrum for the rocker by reason of its location off the center thereof, and the connection of the bushing and the rocker to the arm D is effected through the medium of a bolt H, which is headed at its inner end to bear against a metallic washer or wear-plate I and extends through the said wear-plate, bushing G, and arm D, as shown. At its outer end the said bolt H is preferably equipped with a nut J and washer K, although it may obviously be secured in any other suitable manner.

M is a spring which is provided at one end with a lateral arm t, which is let into a socket to in the rocker-arm D and adj ustably fixed with respect thereto through the medium of a binding-screw 'v. The opposite free end of the said spring is disposed below the lateral pin 0 of the rocker member E, and consequently it will be seen that on the return movement of the shuttle the spring is calculated to cushion the picker-staff and rocker, and thereby check the shuttle with but a minimum amount of shock and jar. It will also be noticed that by virtue of the adjustability of the spring the cushioning of the staff and rocker and the retardation of the shuttle at the completion of the return movement thereof may be readily regulated.

In the practical operation of my improve ments the rocker operates at the completion of the forward movement of the picker-staff in the lay to return said staff to its initial position. This is due to the eccentric mounting of the rocker, for, as Will be seen, it is lifted into the position shown by broken lines in Fig. 1 when the picker-staff is thrown forwardly and when the said staff is released tends to fall, and thereby returns the staff to its initial position (shown by full lines in Fig. 1) ready for the impact of the shuttle. When the shuttle strikes the picker-staff, the pin 0 of the rocker impinges against the checkspring M, with the result that the rocker and picker-staff are cushioned and shock and jar reduced to a minimum.

It will be appreciated from the foregoing that my improvements are very simple and inexpensive and that they are readily applicable to the rocker-arms and pickenstaffs of looms at present in use; also, that the said improvements are calculated to materially prolong the usefulness of the picker-staff of a loom.

I have entered into a detail description of the construction and relative arrangement of the parts comprised in the present embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific con struction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having described my invention, What I claim, and desire to secure by Letters Patent, 1s-

1. The combination of a bracket or rockerarm, a picker-staff, a rocker carrying the staff and fulcrumed eccentrically on the bracket or rocker-arm at one side thereof; said rocker having a lateral projection on its side adjacent to the bracket or rocker-arm, and the check or cushioning spring conuecte at one end to the bracket or rocker-arm and having the free portion arranged to be engaged by the lateral projection of the rocker.

2. The combination of a bracket or rockerarm, a fulcrum projecting laterally therefrom, a picker-staff, a picker-rocker comprising a member mounted eccentrically on said fulcrum and provided with a lateral projection, a staff-carrying member connected to the fulcrumed member, and means for adj ust ably fixing the staff-carrying member and the stafi with respect to the other member to position the staff in the lay, and a check or cushioning spring connected to the bracket or rockerarm and arranged to be engaged by the lateral projection of the rocker.

3. The combination of a bracket or rockerarm, a picker-staff, a picker-staff rocker comprising a member fulcrumed on the bracket or rocker-arm, and having serrations on its inner face, a staff-carrying member also having serrations on its inner face to engage those of the fulcrumed member, and transverse bolts arranged off the center and extending through slots in one member, and transverse bolts arranged off the center and extending through slots in one member, and connected to the other member.

4. The combination of abracket or rockerarm, provided with a slot, a rocker having a transverse circular aperture, a picker-staff carried by the rocker, a bushing arranged in the circular aperture of the rocker and having an angular portion disposed in the slot of the bracket or rocker-arm, and a bolt extending through the bushing and bracket, and connecting the rocker the bushing and bracket, substantially as specified.

5. The combination of a bracket or rockerarm,a picker-staff,a rocker comprising a member eccentrically fulcrumed on the bracket or rocker-arm, a second member, a channel-iron straddling the picker-staff, a central bolt extending through and connecting the channeliron, the picker-staff and said second member, and bolts arranged off the center and connected to one member and extending through slots in the other member, and a check-spring connected to the rocker-arm and arranged to be engaged by a lateral projection on the rocker.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- DQSSGS.
